Method for operating two drives and motor vehicle having two drives, which operate on wheels decoupled from each other

If two (in particular electric) drives operate on wheels decoupled from each other in a motor vehicle, the drives should have an identical construction and the same properties. If however one drive is stronger than the other, distribution factors other than 0.5 must be defined for correcting the cor...

Zusammenfassung:	If two (in particular electric) drives operate on wheels decoupled from each other in a motor vehicle, the drives should have an identical construction and the same properties. If however one drive is stronger than the other, distribution factors other than 0.5 must be defined for correcting the corresponding target torque for the two drives, in other words the fraction of a total torque. According to the invention, said distribution factors are determined while the motor vehicle is in operation. For this purpose, a steering angle and a further parameter such as the lateral acceleration or the yaw rate are determined and a check is performed to determine if the further parameter has the correct functional dependency with the steering angle.
